Streaming Camera Resilience, LL-HLS Review & Scoreboard Performance

· Build 879

Live View (LL-HLS)

  • Low-latency mode now behaves like a DVR — drag the timeline into the past and playback switches to the full session history; Jump to Live returns to the low-latency stream
  • The player recovers automatically after a camera dropout splices the slate in — no more toggling LL-HLS off and on to get the live picture back
  • Opening Analyse right after starting a session now loads and plays automatically instead of needing a Jump to Live press
  • The vertical timeline ruler and playhead stay stable when zoomed in on a live LL-HLS session
  • Jump to Live lands at a consistent distance behind live even after camera dropouts (all players, including the session page)

Fallback Slate

  • Camera dropouts are detected in about 3 seconds (previously ~10) — less frozen frame before the slate appears, and less live-view drift afterwards
  • The slate is generated to match the source stream exactly (profile, pixel format, colour) so re-encoded and stream-copy recordings both survive dropouts cleanly
  • Network (RTSP/SRT) cameras now get dropout protection too — previously only publishing devices did
  • Ships with default slate artwork; choose between artwork, your own image, or a test pattern, and position the slate text from Settings

Streaming Cameras

  • Publishing devices (Piston iOS app, IP cameras, OBS) stay connected through session starts and stops — recordings no longer open with ~10 seconds of slate while the device reconnects
  • Software updates no longer restart the streaming subsystem unless it actually changed, so connected devices ride through updates
  • Deleting a camera cleans up its slate and streaming registrations

New Session

  • A "Publishing Now" row lists devices that are live right now — one tap selects the camera, with a pulsing live badge on its pill; updates every few seconds as devices come and go
  • The session-start countdown is back, ending with "Starting <session name>" — and the New Session page is protected against one broken widget disabling the rest

Scoreboard

  • Scoreboard recordings on streaming cameras no longer add latency to the live HLS view
  • Burning the scoreboard into both live and recording costs roughly half the CPU it did

Tools

  • Create Session From Movie now offers the organisation picker to every user, preselecting the organisation you signed in under
  • Creating a camera from a stream shows a progress splash instead of a silent pause
